LXC and SSVM/CPVM on the host
Ok I think we have to look at this further. I'll stop hijacking other
threads.
I am trying to get the SSVM/CPVM to run on a LXC host. The SSVM/CPVM
starts, get IPs, but then CloudStack kill them for some reason. Yes, I
use the 4.2 images :
2013-10-21 16:19:21,605 DEBUG [agent.manager.AgentManagerImpl]

2013-10-21 16:19:21,609 DEBUG [agent.manager.ConnectedAgentAttache]

I transferred the host to KVM, and now the same SSVM/CPVM images are
running fine for the last 30min ( so I assume it works fine...).
Something seems to be wrong with the LXC side :S
Anyone wants to invest some time to troubleshoot? I'll open a ticket also.

According to the feature page on the wiki, the KVM images are supposed
to be used... or maybe I understood it wrong.

Re: LXC and SSVM/CPVM on the host
Posted by Francois Gaudreault <fg...@cloudops.com>.
If this is the case, then you should remove the ability to create LXC
zones or clarify the documentation about that.
According to the wiki page:
Each of the different hypervisors currently have their own System VMs.
These system VM images are used to run a console proxy, secondary
storage, and router VMs.
We discussed the possibility of creating System VMs for LXC. There was
concern with the complexity and potential issues involving iptables for
the router inside an LXC container. As an intermediate solution we are
going to use KVM System VMs inside the LXC Cluster.
So we need a KVM cluster to run the VMs? (Added the author of the feature)

Re: LXC and SSVM/CPVM on the host
Posted by Chiradeep Vittal <Ch...@citrix.com>.
As far as I understand, in an LXC scenario, the system vms are expected to
run on real hypervisors.
You can always use the QuickCloud way to not use system vms at all.
